After Liang Xuan passed away, Yu Wang lost his lover. Four years later, he still could not get over his grief. Liang Xuan and his ex-wife's son Weng Yanlin suddenly came to "take care of" his life. Liang Hyun was Yu Wang's teacher back then. Many people were very optimistic about their relationship and thought they could get married.

And Weng Yanlin fell in love with Yu Wang within four years after the death of his father Liang Xuan.
There are two lines, one line between Liang Xuan and Yu Wang in memories, and one line between Weng Yanlin and Yu Wang in reality.
